Red blood cells are one of the very few body cells that don’t have a? This is in my biology HW Help

Answer:

Clouds form nuclei of condensation, where partial pressures of water accumulate.

Explanation:

When the partial pressure of water increases, it condenses in large quantities and due to differential pressures with the pressures of the earth's surface, rains or sudden changes are triggered.

Answer:

b

Explanation:

because it is science and I am in high school and I got this question

The "subduction zone" will not be a type of plate boundary.

A subduction zone occurs when two tectonic plates collide and one plate dives through into the mantle beneath another plate.

The boundary among two plates would be known as a tectonic plate boundary. The plate is moving slowly, continuously, and in a variety of directions.

Therefore, the "subduction zone" will not be a type of plate boundary.

Homologous structures provide evidence for common ancestry, whileanalogous structures show that similar selective pressures can produce similaradaptations (beneficial features). Similarities and differences among biological molecules (e.g., in the DNA sequence of genes) can be used todetermine species' relatedness.

Evidence for evolution is provided by homologous structures. These are structures shared by related organisms that were inherited from a common ancestor. Other evidence for evolution is provided by analogous structures. These are structures that unrelated organisms share because they evolved to do the same job.

How do homologous and analogous structures show evidence for evolution?

Answer:

1. Purple petals

2.Purple petals

3. I can't rly tell if that is a lowercase of uppercase p but if they are lowercase then white and if they uppercase then purple

4. Brown eyes

5. Brown eyes

6. Blue eyes

Explanation:

If there are uppercase letters at all the trait is dominant and vice versa for lowercase

Answer:

Cytokinesis, or “cell motion,” is the second main stage of the mitotic phase during which cell division is completed via the physical separation of the cytoplasmic components into two daughter cells. Division is not complete until the cell components have been apportioned and completely separated into the two daughter cells. Although the stages of mitosis are similar for most eukaryotes, the process of cytokinesis is quite different for eukaryotes that have cell walls, such as plant cells.

Tree: Kapok Tree

Explanation:

Cellular structure: https://flexbooks.ck12.org/cbook/ck-12-biology-flexbook-2.0/section/2.9/primary/lesson/plant-cell-structures-bio (please refer to this link for information about plants cellular structure).

The plant cell is very similar to animal cells, they share the same features such as a nucleus, mitochondria, endoblasts, Golgi bodies, and lysosomes. Some differences between plant and animal cells are vacuoles, which are sacks that contain sugars, fluids, and water. When vacuoles are full the plant flourishes but when it dries up, so does the plant.    

Location: All over the Amazon, there are more trees in this rainforest then there are stars in the Milky Way galaxy.

Scientific name: Ceiba pentandra

Common name: kapok or silk-cotton tree

NOTE: Some of these questions were kind of redundant, I mean location, WHAT! The first part of this question literally said find a leaf or tree LOCATED IN THE AMAZON. Also, for the cellular structure one, all plants have to same cellular structure.

Answer:

Natural selection

Explanation:

Answer:

The awnser is Natrual Selection :)

Explanation:

Hi here is your awnser: Natural selection is the process by which organisms with variations most suited to their local environment survive and leave more offspring. In natural selection, the environment—not a farmer or animal breeder—influences fitness. Well-adapted individuals survive and reproduce.

Answer:

Normal level of calcium in the blood.

Explanation:

The normal range of PTH levels means that there is normal amount of calcium is present in the blood. If the PTH level is too high it means that the levels of calcium in the blood is very low while on the other hand, if the levels of PTH is low it means that the level of calcium in the blood is too high so that's why normal range of PTH level means normal level of calcium in the blood.

Specialized cells of one type divide to produce specialized cells of another type is the process that produces stem cells.

Stem cells in the bone marrow produce a variety of blood cells through the process of specialization in which specilized cells are produced that can perform a specific functions in the body.

So we can conclude that option C is the right answer.

Answer:  Small Intestine

Explanation:  Digested chyme from the stomach passes through the pylorus and into the duodenum. Here, chyme will mix with secretions from both the pancreas and the duodenum.

Answer:

it should be C

Explanation:

I hope this helps. Let me know if I am wrong

Answer:

A liver cell

Explanation:

The cell that is most likely to be in G0 phase is the liver cell. That is because it only divides every year or two. However, a stomach-lining epithelial cell divides more than twice a day which means that it wouldn't usually be in the G0 phase.

hope this helps and is right :)

p.s. I really need brainliest

The cell that is likely to be going in Go phase is liver cell as it is the phase in which the cells that stops dividing either temporarily or permanently enters.

The Go phase denotes a cellular state that occurs outside of the replicative cell cycle.

Traditionally, cells were thought to enter G0 due to environmental factors such as nutrient deprivation, which limited the resources required for proliferation. As a result, it was regarded as a period of rest.

Only 1 hepatocyte in 20,000 (0.005%) in a healthy adult liver is in the cell cycle.

The remainder are dormant, in the G0 state. Hepatocytes reenter the cell cycle after partial hepatectomy, progressing from the G0 to the G1 phase.

The liver cell is most likely to be in Go phase because it is the phase in which cells stop dividing either temporarily or permanently.

Thus, liver cell will enter Go phase.

Answer:

More massive then Earth, and Has a tilted axis.

Explanation:

Answer:

The second trophic level consists of organisms that eat the producers. These are called primary consumers, or herbivores. Deer, turtles, and many types of birds are herbivores. Secondary consumers eat the herbivores. Tertiary consumers eat the secondary consumers.

Explanation

An animal that eats producers is called herbivore. Therefore, option (D) is correct.

Herbivores eat plant matter such leaves, stems, fruits, and seeds. These organisms get energy and nutrients from producers, the main source of organic matter in ecosystems.

Cows, rabbits, deer, and many insects are herbivores. Herbivores transform plant biomass energy into a form that higher trophic levels can consume, making them vital to ecosystem energy and nutrient cycles. Therefore, option (D) herbivore is the correct option.

Kepler's Third Law: the squares of the orbital periods of the planets are directly proportional to the cubes of the semi major axes of their orbits. Kepler's Third Law implies that the period for a planet to orbit the Sun increases rapidly with the radius of its orbit.

Answer:

your answer would be B.  the vascular tissue

Explanation:

There are two principal tissue types that make up the veins of plants: The xylem moves water and minerals. This flows from the plant’s roots upwards. The phloem moves food energy around the plant. This flows in whichever direction the plant needs it to flow. These two tissue types make up the vascular bundle of the plant.
